Poterrioochromonas sp., isolated from Microcystis cultures in 2002, was described with LM, SEM, TEM. The grazing characteristics of this strain were also observed in laboratory experiments. The results showed that this strain has the representative features of the genus except for the lorica, and the most conspicuous feature of Poterioochromonas sp. was about the chromatophores.
